  1. Bed Bugs and IPM CAN MAKE STRANGE BEDFELLOWS WAYNE WALKER ASSOCIATE CERTIFIED ENTOMOLOGIST UNIVERSITY OF FLORIDA DEPARTMENT OF HOUSING AND RESIDENCE EDUCATION

  2. BED BUGS • HOW MANY OF YOU HAVE SEEN A LIVE BED BUG? • HOW MANY OF YOU HAVE EXPERIENCED A BED BUG INFESTATION? • HOW MANY USE A CONTRACTOR FOR PEST MANAGEMENT?

  3. WHY DO WE NEED IPM • INCREASED RESISTANCE TO CURRENT INSECTICIDES • EXPOSURE OF RESIDENTS TO INSECTICIDES • SUSTAINABLE SOLUTIONS

  4. WHERE DO THEY COME FROM? WHY ARE THE PROBLEMS SO SEVERE? BED BUGS ON CAMPUS

  5. USED FURNITURE

  6. INTERNATIONAL TRAVEL

  7. LOCAL COMMUNITY

  8. WHY ARE THE PROBLEMS SO SEVERE? • Important Points. • Lays 3 to 5 eggs a day • Total days from egg to adult is about 30 at 80.6˚ F. • 5 molts from nymph to adult • Can live well over 6 months without feeding (some reports over 18 months)

  9. HOW SMALL ARE THEY? • ADULT IS 3/16 INCH LONG • 1ST INSTAR NYMPH IS ABOUT THE SIZE OF A PERIOD AT END OF SENTENCE • EGGS ARE 1-2 MM

  10. TEMPERATURE EFFECTS -Below ~55˚ F Development stops -Above ~99˚ F Development stops -Thrive at temps between ~68˚ F - 80˚ F -Die at Temps > 113˚F or < 32 ˚F

  12. Equipment for Heat Treatment 6 polystyrene sheets 2 heaters 2 box fans 1 oscillating fan Extension cords and power strip

  13. Temperature Monitoring Thermometers Data Loggers

  14. Room Setup for Heat Treatment Vials of Bed Bugs

  15. Room Setup Under pillows on mattress • Live bed bugs • Data loggers • Thermometer sensors • Placement In cabinet Under mattress

  16. Placement of Fans and Heaters

  26. All bed bugs died

  27. Equipment • 2 Space heaters • $99.90

  28. Equipment • 6 Polystyrene sheets (4 by 8 ft) • $137.76

  29. Equipment • 2 Box fans • $27.34

  30. Equipment • 1 Oscillating fan • $29.95

  31. Equipment • 2 Thermometers • $17.94

  32. Equipment Costs$312.89 • 2 Space heaters • 6 Polystyrene sheets • 2 Box fans • 1 Oscillating fan • 2 Thermometers • 2 Extension cords; power strip • Duct or packing tape

  33. THE SECURITY THAT THE BED BUGS ARE DEAD PRICELESS

  34. ROOM TREATMENT • VACUUMING • STEAMING • APPLYING A RESIDUAL

  35. VACUUM THE CARPET • THOUROGHLY VACUUM THE CARPET AREAS • CAN BE BEFORE OR AFTER THE HEAT TREATMENT • DISPOSE OF THE VACUUM BAG

  36. STEAM TREATMENT • PULL THE CARPET BACK FROM BASEBOARDS • STEAM ALONG ALL EDGES AT THE JUNCTION OF CARPET AND WALL

  37. RESIDUAL APPLICATION • APPLY RESIDUAL INSECTICIDE ALONG JUNCTION OF WALL AND FLOOR • APPLY DUST BEHIND ALL WALL PLATES

  38. WHICH RESIDUALS • MOSTLY DUSTS WITH SILICA GEL AND PYRETHRINS • WHITEMIRE TRI-DIE AND DRIONE ARE PREFERRED • DELTA DUST AND BORIC ACID ARE NOT AS EFFECTIVE

  39. WHOLE ROOM HEAT • THERE ARE COMPANIES THAT ARE PERFORMING WHOLE ROOM HEAT • TWO DIFFERENT ENERGY SOURCES • PROPANE • ELECTRICITY

  40. WHOLE ROOM HEAT USING PROPANE GAS • WORKS GREAT IF ALL ROOMS ARE GROUND FLOOR • NEED A READY SOURCE OF PROPANE • MAY TAKE UP TO 24 HOURS

  41. WHOLE ROOM HEAT USING ELECRICITY • 115 VOLT HEATERS REQUIRE 6 15 AMP CIRCUITS TO OPERATE • 460 VOLT HEATERS NEED A GENERATOR • GETS RATHER EXPENSIVE

  42. MANUFACTURERS • Temp Air – http://www.temp-air.com/thermal/index.asp • Pest-Heat (manufacture of heat generating equipment) • http://www.pestheat.com/index.html • ThermaPureHeat – http://www.thermapure.com/bedbugs.php

  43. ELEMENTS OF IPM • Education • Communications • Inspection • Identification • Exclusion • Sanitation • Treatment Strategy • Evaluation

  44. EDUCATION • Institutional staff • Pest control provider • Residents

  45. COMMUNICATIONS • Key element between participants • May take a variety of forms • Addresses problems, solutions, and prevention

  46. INSPECTION • Performed on an as needed basis • Results documented • Provides early intervention and validation of success

  48. IDENTIFICATION • Sample of pest is important • Proper ID is vital • Leads to proper plans for control

  49. EXCLUSION • DIFFICULT TO DO FOR BED BUGS • WELL MAINTAINED FACILITY HELPS GREATLY • SIMPLE THINGS CAN HELP

  50. TREATMENT STRATEGY • Developed with safety as important factor • Utilizing all of IPM tools • Can this strategy be sustained
